Reaction Steps

8.55 g (22.5 mmol) of 1,4-bis(3'-tert-butyl-5'-methyl-4'-hydroxyphenyl)but-2-ene in 100 ml of ethyl acetate are hydrogenated over 1 g of Pd/C (5%) at room temperature under atmospheric pressure. After 30 minutes, the uptake of hydrogen has ended. The reaction mixture is filtered over Celite and the resulting filtrate is concentrated. Crystallization of the crude product from acetonitrile gives 6.6 g (77% of theory) of 1,4-bis(3'-tert-butyl-5'-methyl-4'-hydroxyphenyl)butane of melting point 106°-107° C.
